SHEET-METAL HOOP.

Specification of Letters Patent.

Patented Feb. 29, 1916.

T 0 all whom t may concern:

Be it known that I, EDWARD l. BnAoDooK, a citizen of the United States, residing in Vinchester, county of Middesex, and State of Massachusetts, have invented an Improvement in Sheet-Metal Hoops, of which the following description, in connection with the accompanying drawings, is a speci lication, like letters on the drawings repre senting like parts'.

This invention relates to a sheet metal hoop for barrels, tubs, pails and the like, and has for its object to provide a sheet metal hoop, which is light, inexpensive, strong and especiallyT applicable for use as the chime hoop. To this end the hoop is made from a sheet metal blank or strip, and is provided at one side or edge with a fold, which is corrugated or bent transversely to form outwardly extended striking projections, for the reception of blows of a hammer or other tool, by which the hoop may be driven onto the barrel or other receptacle. The ends of the band or strip may be secured together in any suitable manner, but it is preferred to fasten them together by means of a key, which is crimped to lock it against accidental displacement, as will be described. The sheet metal hoop may be reinforced at its folded edge by a wire, which is located in the fold as will be described. These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is an elevation of a portion of a barrel provided with a hoop embodying this invention. Fig. 2, an enlarged plan of a portion of the hoop shown in Fig. 1. Fig. 3, an enlarged elevation of the portion of the hoop shown in Fig. 2. Fig. et, a longitudinal section on the line @1 -1, Fig. 3. Fig. 5, an enlarged cross section on the line 5-5, Fig. 3. Fig. 6, a plan of the hoop shown in Fig. 1. Fig. 7, an enlarged detail in section to be referred to, and Fig. S, a detail of the blank from which the hoop is formed.

Referring to the drawings, a represents a sheet metal hoop embodying this invention. The hoop c@ is provided at one edge with a folded portion, preferably shaped to form a hollow bead b substantially circular in cross section and in which is located a wire o, and the folded portion is inade of suiiicient width to form a ange or lip LZ, which eX- tends from the bottom of the bead b and is pressed against the body portion 10 of the hoop to obtain a hoop having a body portion provided with a double thickness of metal below and in the immediate vicinity of the bead in the hoop so as to materially strengthen the body portion of the hoop at its upper end. The bead b and the wire o contained therein are corrugated or bent to form outwardly extended projections 12, which form striking projections for the reception of the blows of a hammer ror other tool, by which the hoop may be driven onto the barrel 13 or other receptacle.

Provision is made for the ends of the bead Z) to be brought close together while allowing for the overlapping of the ends of the hoop. For this purpose, the sheet metal portion of the hoop is made from a sheet metal blank or strip 14, see Fig. 8, which has portions removed from one side at its opposite ends, to form end portions 15, 16 which are narrower than the intermediate body portion of the strip o1.' blank, so as to form a projecting portion 17 at one sidev of the strip or blank, which is employed to form the hollow bead and the lip (Z. r1"he ends 15, 16 of the metal strip or blank are designed to overlap and may be fastened together in any suitable manner, but it is preferred to secure them together by a metal key 18, which is passed between retaining webs 19, formed by making a plurality of parallel slits 20 in the end portions 15, 16, as shown in Figs. 3, 4 and 5. To prevent the key 18 from being accidentally displaced, it is bent or crimped between its ends, after the manner represented in Fig. 5, to form a plurality of locking shoul ders 21 which engage the walls of the slits 2() in the end portions 15, 16. The key may be bent or crimped by subjecting the overlapping ends 15, 16 to one or more blows on the inner side of the hoop, and these lows may and preferably will be suflioiently heavy to bring the webs 19 on the inner side of the key substantially fiush with the inner side of the hoop, so as to leave the hoop smooth on the inner surface and enable it to lie close to the barrel at the overlapping end portions.

In the manufacture of the hoop shown in Fig. 1, the projecting edge portion 17 of the blank or strip 14 is folded about the wire c, which is arranged with relation yto the blank 14e, so that the ends of the folded bead b are bridged by the wire, whose ends meet at a point in the bead where the latter is not broken as represented in Fig. 7.

From the above description, it will be observed that the body portion of the sheet metal hoop may be made thin and light,

vwhile its folded edge portion is materially strengthened and capable of withstanding a severe blow, which especially fits the hoop for use as a chime hoop, while the outwardly extended projections 12 afford substantial surfaces for receiving the blows of the hammer or other tool with which the hoop-is driven onto the barrel. "While it is preferred to use the reinforcing wire c, it is not desired to limit the invention in this ree spect, as a very serviceable hoop may be produced from the sheet metal blank alone, by .providing the corrugated bead at one edge.v

By reference to Figs. l and 3, it will be observed that the flange or lip Z practically forms at the upper part of the body portion of the hoop a supplemental hoop, which is in contact with the body portion of the main hoop in the immediate vicinity of the fold or bead, and, as a result, this lip or iiange materially strengthens the body portion of the hoop just below and in the immediate vicinity of the fold or bead and reinforces the body portion ofthe hoop so as to prevent the upper portion of the body po-rtion of the hoop being bent outwardly away from the barrel when the chime hoop is driven onto the same and the upper` portion of the chime hoop is not supported by the barrel.

yClaims:

l. A metal hoop comprising a sheet metal band or strip having at its opposite ends, portions which are narrower than the intermediate :portion of said strip to form on one side of the strip a projecting portion which is foldedto form a hollow bead having its opposite ends removed from the opposite ends of the metal strip, to leave end portions which project beyond the ends of the hollow bead, means for securing the projecting end portions together with the ends of the hollow bead in proximity to and opposing each other and with one of the projecting end portions extended under one end of the beaded portion of the strip on theV outer side ofthe strip and with the other projecting end portion extended under the opposite end of the beaded portion of the strip on the inner side of the latter, and a wire in said hollow bead extended from one end of the hollow bead into the opposing end of said bead, and corrugations in said bead and wire forming outwardly extended projections.

2. .A metal hoop comprising a sheet metal band or strip having at its opposite ends portions which are narrower than the intermediate portion of said Strip to form`V on one side of the strip a projecting` portion whichis folded to form a hollow bead having its opposite ends removed from the opposite ends of the metal strip, to leave end portions which project beyond the ends of the hollow bead, means for securing the projecting end portions together with the ends of the hollow bead inproximity to and opposing each other and with one of the projecting end portions extended under Y Y EDWARD I. BRADDOCK.
